3 Claims.

The present invention relates to a seal for bags, such as those in whichcoins are shipped to banks. These bags are made of flexible material andrequire to be closed by means that encircle the mouth of the bag, afterwhich a sealing member of compressible material is deformed to lock orseal the means that encircle the mouth of the bag. Heretofore, a strand,usually of fibrous material, has been employed as the bag-encirclingmeans. The main object and feature of this invention is to produce astructure in which a fiat ribbon-like sheet-material member can beutilized as the bag-encircling means.

In the accompanying drawings, the invention is shown in a concrete andpreferred form, in which:

Fig. l is a view in side elevation of a seal embodying a preferred formof the invention;

Fig. 2 is a vertical sectional view, substantially on the plane of line22 of Fig. 1;

Fig. 3 is a horizontal sectional view, substantially on the plane ofline 33 of Fig. 2;

Fig. 4 is a bottom plan view of the guard-member;

Fig. 5 is an enlarged view of parts of Fig. 2; and

Fig. 6 is a perspective view showing the seal applied to a bag.

indicates a sealing-member of relatively compressible material such aslead, said sealingmember being provided with a longitudinal slot 2! openat both ends. 22 indicates a flat ribbonlike sheet-material member ofrelatively nontearable material such as steel. Member 22 is anchored atone end 23 in said sealing-member, the anchoring operation beingpreferably performed by imbedding the sheet-material member in thesealing-member during the process of molding or casting the latter. 24is a guardmember, of relatively non-compressible material, interposedbetween the bag and the sealing-member, and is provided with an opening25, here of rectangular shape, slightly wider than the width ofsheet-material member 22. Sheet-material member 22 has its free end 26threaded through opening 25 of guard-member 24, is formed into a loop,and is then threaded back again through said opening 25, and thenthrough and out of slot 2! of sealing-member 20.

The bag-encircling loop of sheet-material member 22 is now passed aroundthe mouth of the bag, and is then tightened by pulling on its free end26 until the mouth of the bag is properly constricted. It now remains todeform sealingmember 20 so as to complete the sealing operation.However, there is a momentary interval between the completion of thepull on free end 26 and the act of deforming the sealing-member, and,owing to the slippery material of which the sealing-member and thesheet-material member are made, there is a tendency for thesheet-material member to be retracted out of slot 21 in thesealing-member. To overcome this, means are provided to prevent suchretraction out of the slot of said sealing-member, before saidsealingmember is deformed, such means including a detent-and-perforationconnection between said guard-member and said sheet-material member.Said sheet-material member is therefore provided with one or moreperforations 21. As a matter of fact, there is, in this case, alongitudinal series of perforations so that the seal may be applied todifferent sizes of bags. 28 indicates a detent, carried by guard-member24, arranged adjacent to opening 25 of the guard-member. As indicatedpreviously, opening 25 of the guard-member is slightly wider than thewidth of sheetmaterial member 22, and the other dimension of saidopening 25 is such that the guard-member can be tilted on thesheet-material member, and held by the finger of the operator, so as toprevent detent 28 from entering any of the perforations 21 until theloop has been tightened sufilciently around the bag, at which time saiddetent 28 will enter a perforation 21 and will thereby preventretraction or part withdrawal of the sheet-material member out of theslot, thereby enabling the operator to deform the sealingmember and thusfinish the sealing operation.

I claim:

1. In a bag seal, a sealing-member of compressible material having aninterior slot, open at both ends; a sheet-material member of nontearablematerial, to be formed into a bag-encircling loop, having one endanchored in the sealing-member, its other end to be passed through andout of the slot of said sealing-member; a guard member to be interposedbetween the bag and said sealing-member, said guardmember having anopening through which said sheet-material member passes; and means toprevent retraction of said sheet-material member out of the slot of saidsealing-member, before the latter is deformed, including adetent-andperforation connection between said guard-member and saidsheet-material member.

2. In a bag seal, a sealing-member of compressible material having aninterior slot, open at both ends; a sheet-material member of nontearablematerial, to be formed into a bag-encircling loop, having one endanchored in the sealing-member, its other end to be passed through andout of the slot of said sealing-member, said sheet-material memberhaving a perforation; and a guard-member to be interposed between thebag and said sealing-member, said guard-member having an opening throughwhich said sheet-material member passes, said guardmember having adetent adjacent its opening to engage the perforation in saidsheet-material member.

3. In a bag seal, a sealing-member of compressible material having aninterior slot, open at both ends; a sheet-material member of nontearablematerial, to be formed into a bag-encircling loop, having one endanchored in said sealing-member, its other end to be passed through andout of the slot of said sealing-member, said sheet-material memberhaving a longitudinal series of perforations; and a guardmember to beinterposed between the bag and said sealing-member, said guard-memberhaving an opening through which said sheet-material member passes, saidguard-member having a detent adjacent its opening to engage aperforation in said sheet-material member.
